the window frame A directly adjacent the sash carrying bracket 5. Thispanel 9 is equipped at adjacentits lower edge with a.

conventional electrical push button switch Ci Arranged uponthe face ofthis panel OF WILKES-BARRE, PENNSYLVANIA.

9 adjacent the outer vertical edge thereof is '8 a diagonally extendingguide member 10 arranged horizontally through the bottom of which is astop bar 11. Securedto theface of this panel9 inwardly of the guide 10and at its upper end is a; diagonally extending elon gated tongue 12 ofspring material, the lower end thereof being free from the panel asclearly indicated in Figures 1 and 3, said lower end of this springtongue terminating directly in front of thebutton element of the pushbutton switch C. This tongue 12 is so bent as to normally extend in anoutward direction away from thepanel 9 and in light engagement withtliebutton of the switch C so that the normal position of the switch will beoff, However, when the lower end of this tongue s 'swun'glmwardly theswitch will be closedfor completing an electrical circuit to a suitableably of the character alarm, prefer- The panel 9 at the edge adjacentthesash B is equipped with an outwardly extending threaded pin 13 uponwhich is pivotally'S: cured a block 14, the outer edge of this, blockbeing formed with a horizontal tongue 15 that projects beyond the springtonguelZ and that is guided at its outer end within the guide pin abovethe stop bar 11., The surface of the tongue12 above the stopbar 11 isbeveled so that as the tongue 15 is moved downwardly it will stillengage the tongue" y g as forv operatmg the push button and cause theloweren'd thereof to sprin inwardly switch C.

indicated. in Figure 5- asherei'nafter more fully described.

The inner edge ofthe piv'ot block 14 is 3 also equipped with a tongue1-7 which tongue is pivoted within the adjacent bifurcated end of arelatively H-shaped block 18 byreason of a vertical pivot-19l Theopposite bifurcated lUlr end of this block 18 isadapted for engagementover the swivel pin 7 of the sash bracket 5. When the pin 7 of thebracket 5 is turned so that the key tongue 8 will overlie the edge ofthe bifurcation within the block, said block "will be prevented frombeing swung upon thepivot 19. Moreover thiswill afford such a connectionbetween the sash and said block 18 as to. cause, the pivoting of theblock '14 upon the pivot 13 whenever the sash B is raised, for ashereinbefore stated closing the push button switch G.

Furthermore as the sash B is raised the tongue 15 of the block 14 willengage the stop bar 11 for limiting the raising of the sash which willof course prevent any one from entering the window. I

Arranged over the threaded pin 13 at the outer face of the block 1% is acollar 19 secured upon the pin 13 by a wing nut 20. The collar 19 isequipped with an upwardly extending pin 21 while the upper edge of theH-shaped block 18 is also equipped with a pin said pins beinginterconnected by a retrac- File coil spring 23 for the purpose ofautomatically swinging the block 18 away from the bracket 5 when thesame is released from the bracket 5 by turning the pin 7.

The character of signal preferably employed consists of a bell 2 1-located at a convenient point within the dwelling which bell is incircuit with the push button switch C and a suitable source of electricsupplyD,

Also located within the circuit is a suitable control switch E in orderthat the circuit may be broken permanently to the hell even though theswitch C is operated. If desired, the signal may be placed in circuitwith switches located at other windows within the dwelling as generallysuggested by the diagrammatic view, Figure 5.

It will thus be seen that we have provided a highly novel, simple, andeflicientlyoperable sash lock and signal switch actuating device that iswell adapted for all the purposes heretofore designated, even though wehave herein shown and describcd'the invention as consisting of certaindetail structural elements it is nevertheless to be understood that somechanges may be made therein without aifecting the spirit and scope ofthe appended claims. 1

Having thus described the invention, what we claim as new and desire tosecure by Let ters Patent is s I 1. In a device of the characterdescribec, a bracket constructed for attachment to a sash frame, aplatemcmber constructed for attachment to the window frame adjacent saidbracket, a push button switch assoc ated with said plate, an elongatedfinger of spring material connected at one end to said plate andoverlying the button of the push button switch at its lower end, saidfinger being normally swung outwardly at its lower end, a blockpivotally secured to said plate, a tongue upon one end of: the block forengagement over said spring finger whereupon when the block is swungdownwardlysaid tongue will cause the inward movement of thefinger toclose the push button switch and a connection between the block and thesash attached bracket, to cause the swinging ot' the block when the sashis raised.-

2. In a device of the character described, a bracket constructed forattachment to a sash frame, a plate member constructed for attachment tothe window frame adjacent said bracket, a push button switch associatedwith said plate, an elongated finger of spring material connected at oneend to said plate and overlying the button of the push button switch atits lower end, said finger being normally swung outwardly at its lowerend, a block pivotally secured to said plate, a tongue upon one end ofthe block for engagement over said spring finger whereupon when theblock is swung downwardly said tongue will cause the inward movement ofthe finger to close the push button switch and a connection between theblock and the sash attached bracket to cause the swinging of the blockwhen the sash is raised, and means associated with the window frameattached plate to limit the downward swinging movement of the blocktongue to limit the'upward movcment of the sash.

3. In a device of the character described, a bracket constructed forattachment to a sash. frame, a plate member constructed for attachmentto the window frame adjacent said bracket, a push button switchassociated with said plate, an elongated finger of spring materialconnected at one'end to said plate and overlying the button of the pushbutton switch at its lower end, said finger being normally swungoutwardly at its lower end, a block pivotally secured'to said plate, atongue upon one end of the block for engagement over said spring fingerwhereupon when the block is swung downwardly said tongue will cause theinward movement of the finger. to close the push button switch, aconnection bet'weenthe block and the sash attached bracket to cause theswinging ot the block when the sash is raised,.and quick detachablemeans between the block and said sash bracket so that the sash may beraisedor lowered with out causing a pivotal action of the block.
